This is more of a comment (or a question) as opposed to a full blog post, but it occurred to me while reading the last issue of Green Lantern (which was #7) and on seeing one of its alternate covers, that anytime that there is someone seated on a throne (or throne like chair) that there is an added chance that the person (or entity) sitting there has someone of the opposite gender chained at their feet.  Of course this is not universally true, but probably shows up more than is necessary (and to be fair of both the examples listed, these scenes did not actually occur inside the comic.)
